TUCK- MARKER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 256,833, dated April 25, 1882.

' Application filedAugnstl5, 1881. (No model.)

To all whom it may concern: 7

Be it known that I, HARRY O. GooDaIoH, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Tuck-Markers for Sewing- Machines, of which the following is a full description, reference being had to'the accompanying drawings, in which- Figure l is a top or plan view "Fig. 2, a side elevation; Fig. 3, a cross-section on line a: x of Fig.1, looking toward the creasing device; Fig. 4., a detail showing a modified form of the actuating-lever; Fig. 5, a cross-section on line y y of Fig. 4, looking toward the lever.

This invention relates to that class of tuckmarkers in which the actuating mechanism for operating the creasing device consists of a rock bar or red carrying at its end a creasing device and actuated by a lever or arm from the needle-bar, the reciprocating movements of the needle-bar through theactuating lever or arm producing the required rocking movement of the bar or rod to depress and elevate the creasing device and produce the required mark or crease by the combined action of the creasing device and ablade which eoacls with such device.

The objects of this invention are to furnish a connection for the actuating arm or lever with the rock bar or rod which will maintain thetwo in the same relation one to the other with reference to the inclination of the lever or arm for attachment to the needlebar, and at the same time permit the lever to be adjusted longitudinally on the bar or red, the adjustment not afi'ecting the angle of inclination by the change of position of the lever of the bar or red longitudinally; to furnish a connection between the actuating arm or lever and the needle-bar which will allow a slight variation of movement in the needle-bar without producing injury or strain on the parts; to perfect and improve the relative arrangement and relation of the several parts and render their operation more effectual and reliable, and to insure the production of a distinct and clear mark or crease by the action of the creasing devices.

To these ends my invention consists essentially in the combination in a tuck-marker adapted to be attached to the bed-plate of a sewingmachiue, of a rocking bar, a swinging or oscillating arm or lever attach ed thereto, an arched or curved spring connected with said rocking bar, a creasing-wheel carried by said spring, and a plate provided with a creasing-blade,

said parts being organized for operation, as

will more fully hereinafter appear in the de-., tailed description.

The invention embraces otherfeatures which will be fully hereinafter described, and specili cally pointed out in the claims.

In the drawings, A represents the rock bar or red; B, the bearings therefor; .G,'the plate carrying the rock bar or red; D, the base or, guide-plate; E, the sliding-plate carrying the blade, and to which the plate 0 is secured; F, the arm or extension on which the blade is 10 cated; G,- the. actuating lever or arm; H, modification of the actuating lever or arm; a, the spring or spring-arm b, the grooved creasing wheel or devices; 0, the blade; 61, the catch or lip for keeping the cloth down; 6, the slot in the head or socket of the spring a; f, the set-screw for attaching the spring or springarm a; g, the slot in the lever or. arm G; h, the set-screw for attaching the lever or arm'to the rock bar or rod; 1', the longitudinal groove in the rock bar or rod; j, the guide-flange; k, the set-screw for attaching the sliding plate (3 E to the base or guide plate; Z m, the arms or links forming the arm or lever Gr or'H; n, the pivots for the arms or links Zm of thelever H.

The rock bar or arm A is made of round wire or other suitable material having snflicient rigidity not to bend, twist, orbreak easily in use. It is mounted in bearings B, which bearings are located on the plate 0, and may be formed therewith or be independent pieces secured thereto. These bearings are located. at or near each end of the plate G, and furnish a support by which the free end of the bar or red A will be carried'and supported above and clear of the plate E, leaving the bar or rod free to be rocked by the actuating lever or arm without binding in the bearings.

The plate 0 has its rear portion struck up slightly, and this portion overlaps the plate D, and is provided with an elongated slot for v the passage of the shank of a set-screw, 70, by means of which slot and screw the plate 0 is adj ustably attached tothebase or guide plate D,the screw 76 entering a screw-threaded opening therefor in the plat-e D, and this screw is can beloosened slightly and the plateO moved to bring the parts or devices which are carried thereby to any desired position for tucking purposes, and when in position the screw can be tightened and theplate and devices or parts will be firmly secured and held in such position until a new adjustment is desired.

The plate D is provided with a slot to receive a suitable set-screw, by means of which theplate is attached to the bed-plate of a sewing-machine in the usu'al'manner of attaching other styles of tuck-markers. This plate D has its forward edge turned up to form a guide or flange,j,against which the edge of the cloth travels while'bt-ing creased, the same as in other forms of tuck-markers, the flange having a slot in line with the bar or rod A to permit such bar or red to be'moved longitudinally for adjusting purposes.

The plate E is attached to the underside of theplate (J, and the two form a sliding plate by which the required adjustinentsare secured. This plate extends beyond the plate 0 in a forward direction, and its free end has a side extension or arm, F, on the end of which the blade 0 is located, which blade is arranged to beiu line with the creasing device, so as to coact therewith in producing the crease or mark, and'on'this'arm 1 just back of theblade, is a lip or catch, (7, under which the cloth passes, as usual.

The creasing :device shown consists of a grooved wheel, I), the groove of which centers with the blade 0. This wheel is pivoted or 'journaled on the outer or free end of a spring or spring-plate, a, so as to revolve freely when travelingover the cloth. The spring or spring-arm a is bent or curved upward in'such manner as to resist downward movement and create the pressure required to produce the m ark or crease.

This spring or spring-arm may be made of any producing a better and more distinct mark or' crease. This'spring or spring-arm ais secured to theprojecting end of the bar or rod A in suchmanner as to bring the creasing devices in line with the blade, and the socket or'head bywhich it is attached is provided with a slot, 6,. for. the passage of a set-screw, f, which enters the bar or rod A and clamps the socket or head firmly thereto. This slot 6 is for the purposeof adjusting the spring or spring-arm to bringsits free end at the proper elevation for the action of the creasing device, the adjustment being made by loosening the set screw and turning the socket or head in the proper direction to raise or lower the free end of the spring or spring-arm as required to bring the creasing devices at the proper elevation. This adjustment may be found desirable in case the spring or spring-arm loses some of its elasticity and resistance from iise, in which case its outer or free end can belowered and the pressure restored by adjusting the socket or head.

The lever or arm G may be formed from a single piece cast or otherwise made, so as to have two arms or links',l m ,standing at anangle to each other, or it may be made of independent pieces rigidly secured together to form arms or links standing at an angle. One of these arms, Z, has at its outer end a socket or head to receive the bar or rod A, and it is secured to the bar or rod by a set-screw, h, passing through the socket and entering a slot, 2', in the bar or rod, which slot extends the entire length of the bar or rod, the end of the setserew entering the slot and forming a rigid connection betweeu'the arm and the rod or bar. The location of the opening in the socket or head for the set-screw h and the location of the slot z in the bar or rod are in such relation to each other and to the lever or arm G that when the end of the set-screw is in the slot 2' the lever or arm'will stand at the proper inclination in relation the needle-bar for connection therewith, and by thus connecting the lever or arm to the rod or bar it will be seen that-in adjusting the rod for different widths of tuck, when the adjustment is made and the end of the setscrew is locked with the slot 11, the arm or lever will be in correct relation to the needle-bar, so that the time and labor which has heretofore been required in order to adjust these parts properly to produce a correct action of the creasing devices are dispensed with, as all that is necessary to be done is to move the bar or rod forward or back and bring the setscrew in line with the slot and secure the arm or lever and the bar together, when the arm or lever is in correct position for use. This connection, by means of the setscrew it and slot '5, prevents the rod or bar from turning and locks the rod and the lever rigidly, so that the connection will be firm and unyielding, and the set-screw and the slot form a guide by which the arm or lever can be readily and easily set in correct relation to the needle-bar, and

the creasing devices and the connection is one which will not become displaced in use.

In'Figs. 4 and 5 anotherform of actuating arm or lever is shown, in which the two arms or links I m composing it are pivoted at their juncture by a pin or pivot, a, one of which, l, is connected withthe rock-bar by a set-screw, in the manner described for the other form of lever, and the other, m, is connected at its outer end with the needle-bar, the end having a circular opening for the passage of the setscrew' to connect it with the bar. This form of arm is adapted for some classes of machines for ICC which the arm or lever G, having its arms or links rigidly connected, cannot be readily used. When the arm or lever has its parts rigidly connected the part m,which is attached to the needle-bar, is provided with an elongated slot, g, to allow the needle-bar to move without imparting a rocking movement to the rod A, in case the movements of the needle-bar are greater than is required to turn or rock A and operate thecreasing device. When the links or arms lm forming the lever are pivoted together this play is provided for by the pivot, which.

allows the link or arm at to move without acting on the link or arm I.

'In use the marker is adjusted as usual for the desired width of tuck. When adjusted the connection between the actuating-lever and the rock-bar A is made rigid by the set-screw h and groove 1', as described, and the device is ready for use. At each descent of the needlebar the end of the arm or link m will be carried down, which movement, through the link or arm I, rocks the bar A forward and forces the grooved wheel onto the material over the blade 0, forming a crease, and this crease will be very clear ,and distinct by reason of the pressure given to the creasing device and the travel of such device over the material, which last result is obtained through the elastic action of the spring or spring-arm a.

The needle-bars for different styles of machines vary somewhat in the length of their stroke, and this variation is compensated for by the slot 9 when the arms or links are rigid, and by the pivot when such arms or links are so connected that the same form of actuatin g-lever can be applied to the different styles of machines without any change in construction, thereby permitting the marker to be attached to any machine.

By constructing and arranging the several parts as shown and described the free end of the rocking arm is supported above and clear of the carrying-plate. The bearin gs for the rockrod being a considerable distance apart gives the rod a firmer and stronger support to withstand the strain in use. The actuating-lever is connected to the rock-bar so as to be rigid in use, and at the same time the position of the rock-bar can be easily and quickly adjusted longitudinally. No labor is required to bring the aetuating-lever, the needle-bar, and the rockbar in correct relation to each other when the marker has been changed to produce the different widths of tuck, as the slot i and set screw it form a guide to properly set the parts after each adjustment and bring them in correct relation to each other. The actuating lever or arm, through the slot 9 or the pivot n, compensates for any variation in the stroke of the needle-bar, the slot or the pivot permitting the needle-bar to move without acting on the lever, and this slot or pivot also prevents any straining or wrenching of the parts in the event the needle-bar stroke is not correct. The spring or spring-arm which carries the creasing device by its elasticity gives such device a long travel over the material, and also furnishes the means for returning the creasing device to its normal position on the return movement of the rock-bar. The slotted connection for the spring or spring-arm with the rock-bar permits an adjustment of the creasing device to be made as required for use, and all of these features when combined in a tuckmarker render such marker more reliable and effectual in producing the mark or crease.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a tuck-marker adapted to be secured to the bed-plate of a sewing-machine, the combination of a rocking bar, a swinging or oscillating arm or lever attached thereto, an arched or curved spring connected with said rocking bar, a creasing-wheel carried by the free end of the spring, and a plate provided with a creasing-blade, said combination being and acting substantially as and for the purpose described.
